We are given the equation or function <span> y = sqrt (2x + 1). The derivative of the equation is expressed as 

</span><span>1. dy/dt = 0.5 *2 *(2x + 1)^-0.5 dx/dt
</span>when x = 4 and dx/dt =3
dy/dt = 0.5 *2 *3*(2*4 + 1)^-0.5 
dy/dt = 1

2. <span>dy/dt = 0.5 *2 *(2x + 1)^-0.5 dx/dt
</span><span> If dy/dt = 5, find dx/dt when x = 12.
</span><span>    5= 0.5 *2 (2*12 + 1)^-0.5 dx/dt
   dx/dt = 1 </span>

An experimental population of fruit flies increases according to the law of exponential growth. There were 60 flies after the 2n
Mice21 [21]

Answer:

There were 10 flies originally

Step-by-step explanation:

Since we have an exponential growth, we will be having a constant percentage of increase and we can set up the increase at any day using the following equation;

V = I(1+r)^d

where V is the number of flies on a particular day

I is the initial number of flies

r is the constant increase in percentage

and d is the number of days.

So we have for the second day;

60 = I(1+r)^2 ••••••(i)

For the fourth day, we have;

360 = I(1+r)^4 ••••••••(ii)

divide equation ii by i; we have;

360/60 = (1+r)^4/(1+r)^2

6 = (1+r)^2

(√6)^2 = (1+r)^2

1 + r = √6

r = √6 - 1

So we can substitute the value of r in any of the equations to get I which is the initial number of flies

Let’s use equation 1

60 = I(1 + r)^2

60 = I(1 + √6 -1)^2

60 = I(√6)^2

60 = 6I

I = 60/6

I = 10 flies

Which BEST describes the construction of a triangle if given one side length of 10 cm and one right angle?
Colt1911 [192]
Statements that best describe the triangle are the following:
1. It is a right triangle, therefore one angle is equivalent to 90°.
2. We can solve for the measurement of the other leg using the Pythagorean theorem c²=a²+b².
3. We can use SOH CAH TOA theorem in solving the other unknowns.
